you won't get many here that will offer positive suggestions.
one, because you can't use that item, with a WDH. and it sounds like you aren't using a WDH. probably because Honda says you shouldn't, which goes against all other auto/truck manufacturers.
two, because you're probably exceeding the Ridgeline's max tongue weight with your trailer. the 2304 has a "DRY" weight of 569lbs., which is already over the max AND you aren't using a WDH. loaded, it'll be worse.
there should be a max amount printed on the hitch receiver.
even though we loved the Ridgeline, when we shopped for a new tow vehicle, all its limitations and Honda's anti-WDH opinion, were why we decided not to buy one.
